Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions.
Note 2: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 3: Typical values represent most likely parametric norms at V_DD = 3.3V, Ta = +25 degC, and at the Recommended Operation Conditions at the time of
product characterization and are not guaranteed.
Note 4: Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground except VOD, ΔVOD,
VTH and VTL which are differential voltages.
Note 5: t_PLD is the time required by the device to obtain lock when exiting power-down state with an active RxCLKIN.
Note 6: UI – Unit Interval is equivalent to one serialized data bit width (1UI = 1 / 28*RxCLKIN). The UI scales with RxCLKIN frequency.
Note 7: Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the V_DDn (1.8V) supply with amplitude = 100
mVp-p measured at the device V_DDn pins. Bit error rate testing of input to the Ser and output of the Des with 10 meter cable shows no error when the noise
frequency on the Ser is less than 750 kHz. The Des on the other hand shows no error when the noise frequency is less than 400 kHz.
Note 8: Specification is guaranteed by characterization and is not tested in production.
Note 9: Specification is guaranteed by design and is not tested in production.
